"ed new and useful Innprovements in Clips for Stentering hihrchines, of which the itch lowing is e specification.

My invention relates to stentering mnchine clips such, for instenc ias are described and claimed in the specification of United States Letters Patent No. 1,050,755, granted to me. I refer more especially to clips of the character shewn in, and described with reference to, Figures 10, 11,

and 12 of the said specification.

The principal objects of my present ,invention are toliinprove clips of the kin-d referred to so to allow of the openingof the upper jaw, without obstruction, as tar as required to enable the cloth to be convenientljy fed to the clips andthe clips .to be cleaned with facility, and generally to provide a very convenient arrangement of the parts of the clips which will give elii c ient action thereof, and which, whilst preventing undue pressure ofthegnuge-tong11es on the cloth, will provide "efficient pressure of the upper jaw to give improper grip there of upon the cloth. e

According to my invention 1 arrange one of the arms constituting the lever of the gauge-tongues, by which the said lever is centered to the upper jaw, outward of one of the arms by which the said jaw is connected, with its axis so that I can, when so desired, employ but one vertical arm on the body part of the clip. l-ulso provide for theleverof the egeuge tongnes, an abut ment, upon the said "vertical arm, or up right, the said abutment causing the Said gauge-tongues to be liltted when the upper jaw is opened. I also vhinge a cam-piece to the upperjew and provide a spring which puts pressure on the upper jaw, to press the said earn-piece against an ubutment carried by tho'verticel arm, the said parts being so arranged that the pressure which is exerted UPOIL the upper jaw by the spring tails hereinafter explained.

does not exert objectionable pressure cu-pen the gauge-tongues when they rest upon the fabric. l

-I may Pl'OVlClQ a. PI'OJBC-tmg snug at the upper part of the vertical arm to take e bearing against a plate, or the equivalent, and prevent tilting of the clips when the opening levers act to open the clips.

I will describe, with reference to the accompanying drawings, clips made in acto cordance with my invention. Figures 1 and 2- are side elevations shewing parts in difierent positions and Figures and 4:, are, respectively, a front elevation and a plain or iLCOllSlil'LICllOll in which the 135 hot ,y part of the clips is provided with but one vertical arm. Flg'uresfi and 6 shew de- Figures 7 and 8 i are side elevations showing parts in different :eositions and Figures 9 end 10 "t0 are, respectively, a front view and a sectionzil plan, of a lllOdlfiGttl'Oll m'whlch certem of the improvements are applied to a clip having two vertical arms. 7

Referring first to Figures-1 to 6, both inclusive, the body of the clip comprises the :hem link I) and the vertical arms C projecting upward therefrom. The plate- 0 of the lower jaw lies on the body of the chain link D, while the upper jaw B is piveh oted to the chain link D at G by the arm B The lever a of the gauge tongues A have h nges F placed on the arm 13 of the upper awin a manner which will be described later. I so arrange the lever a of the gangetongues, A as to bring one of' its nrms thereof outside one of the arms 13,

of the connection of the upper jaw B with its axis in such ma-ni'ie-r that I can, when so desired, lighten the clip by dispensing with in) one of the vertical arms, constituting, with the cha in him-k1), the body of the clip.- Piv oted on the arm B of the upper jaw at center j is unitary member comprising the o )enin lever J and the wed iu cam J. b a

On the vertical erni, C, I provide an abutment N (see the detail View Figure 5) to engage the part E of one of the arms of the lever aof the gaiige toiigues A, when "the said tongues are beering 011 the cloth and to hold the upper jaw B open until the selvedgeof the cloth moves from under the gauge-tongues. The said abutmentmay for r in the thickness of the elotlrted to the stentering machine.

'Byarranging the said abutment N upon the arm, or upright, C, instead of upon a pin extending across the clip from one ver tical arm, or upright, to another, I avoid obstruction to the opening of the upper jaw B, aswide-ly as may. be required to conveniently feed the cloth .to the clips, or to clean them when required, whilst the improved arrangement of the parts gives a clear space for the spring H, (which exerts pressure on theupper'jaw when closed) and allows thehinge F for the lever a of the gaugeton'gues,or fingers, A, to be placed on the arm 13 voi the upper jaw at such distance from the centre (ir,-on which theupper jaw B turns, as will, whilst giving sufficient leverage for thespring on the upper jaw through the wedging-cam J centered to it at j, prevent thesaid spring causing undue pressure of the gauge-tongues, A on the fabric. A stud K can be provided, below the hinge F for the lever of the gauge-tongues, tocause the said gauge-tongues, tobc raised as the. clip is opened. r lrleferring to l igur'e (tit will be seen that the rod, or tube, constituting thespindle L which turns on the same, centre as the upper jaw andguides the spring H, is slotted for the reception of a curved part, or lnidfeather, M on the wedging-cam J, instead of the said spindle passing through a hole in the part which comprises the wedgingcam; The upper end of the spring, H bears against a shoe h, to allow of free sliding action between it and the curved under part of then'iid-feather M of the cam J Q'\ccording to the modification shown in Figures"? to 10,'bot h inclusive, the arms of the lever a of the gauge-tongues, A can be hinged'to the vertical arm, or upright, orarms, or uprights, of-the body otthe clip instead of to the arm, of the upper jaw which will give a construction which is simpler than that here'inbeiore described and illustrated and avoid the torwardmovement ot the lever of the gauge-tongues. or fingers, when opening and feedingtlie clips. 'lhe forward side of the snug N on the upper jaw B engages the rear side of a snug E on an arm: or the lever a of the gaugeto'ngues, or fingers, A when they are resting on the cloth and, when the said gaugetongucs, or fingers, (on the cloth moving from beneath them) pass through the slots in the plate 0: of the lower jaw, the upper jaw B is released. A snug K on the arm Blot the upper jaw B engages the underside of the snug E to raise the gauge-tongues, or fingers, when the upper jaw B is opened for the cloth to be fed into the clip.

There may be a projecting snug P on the top of the vertical arm, or upright, G (or arms, or one, or both, of such uprights) of the body of the clip to bear against a pla.tc,ror the equivalent, Q, and take the thrust from the clip-openers, or cams, at each end of the machine to prevent tilting of the clips.

'hat I claim is:-

1. In a stentering machine clip having an upper jaw provided with arms hinged to the body part of the elip,a hinged gauge tongue, arms for said gauge tongue, one of said gauge tongue arms being arranged outwards ot one of the upper jaw arms, an abutment on the body partot the clip, and

a projection on said outward gauge tongue arm adapted to engage said abutment when said gauge tongue is resting on the fabric; in con'ibination with a wedging cam hinged to theupper jaw arms, a spring adapted to press said wedging cam against the body part of the clip, and means whereby the gauge tongue is raised as the upper jaw is opened; all arranged so that the pressure which is exerted by said spring upon the upper jaw does not exert objectionable presi sure upon the gauge tongue as it rests upon the fabric.

2. In a stentcring machine clip, a body part having only one vertical arm, an abut ment on said arm, an upper jaw provided with arms hinged to the body part of the clip, a hinged gauge tongue, arms for said gauge tongue, one of said gauge tongue arms being arranged outwards of one of the upper jaw arms, and a projection on said outward gaugetongue arm adapted to ensaid abutment onthe vertical arm of the body part of the clip when said gauge tongue is resting on the fabric, in combination with a wedging cam hinged to the upper jaw arms, a spring adapted to press said wedging cam against the vertical arm of the body part of the clip, and means whereby the gauge tongue is raised as the upper jaw isopencd; all arranged so that the pressure which exerted by said spring upon the upper jaw does not exert objectionable pressure upon the gauge tongue as it rests upon the fabric.

In a stentering. machine clip according to claim 1, apivoted rod slotted at its free end on which said spring is mounted, a slider bearing against one end of said spring, and a mid feather portion of said wedging cam having a curved part lying in the slotted end of said rod and bearing upon said slider.

t. In a ste'ntering machine clip according to claim 1, an opening lever on said wedging cam, a vertical arm on the body part of the clip, and a protecting snug near the top of said vertical arm in combination with a stationary plate against which said snug is adapted to take to prevent tilting of the clip When said opening lever is actuated.

Tn testimony whereof I have signed my name to this specification in the presence of two subseriblng witnesses.
